The Tomb Guardian - Hound of Anubis is an undead creature found in many tombs in Egypt (Act II). It looks like a mummified hyena beast and is a fairly fast, durable and strong melee attacker. Tomb Guardians come in packs of around 3-5 creatures and they can drop the Lupine Claw monster charm.
There is a hero monster called Hesy-su-neb-ef, which is located in a tomb on the Giza Plateau. It is part of the side quest The Missing Brother and a more powerful vairant with an addtional fire attack.
